Closer to home, Saugerties holds its annual garlic tribute, while Margaretville celebrates the cauliflower; in Orange County, the town of Monroe basks in the heady aroma of Liederkranz cheese. If you want to put your town on the foodie-tourism map nowadays, it seems, you have to adopt a particular foodstuff and make it your own.
